7 This invention relates to av distributing the ground. 2 Theseinultipleiconduit's are conduit for use in multiple ducts of conduit sections in Order to permit the taking off of'a single line,'or aplurality'of lines, in a i-"i 5 lateral or vertical direction from a multiple duct conduit formation of an underground- 'conduitline.

n In underground [is a common practiceto employ clay; tile i lo whichare formed in sections-with multiple ducts for carrying "the diflerent' lines, and uniting these tile to form a complete coni duit whiclris submerged and buried under located underground and when it is desired to takeoff a line from one ofthese conduits for the purpose of admitting new oraltered "service into the particular system, it has ment ofbreaking through the entire" line in ,her'etoforebeen necessary to'break into theclay tiles, destroying 'one or more complete sections of the tile, ,withja consequent requireorder to thread such conduits back through the multiple duct tile.

I This" is an expensive operat on, and is the object of this invention to provide a distribution conduit which includes'meansfor permitting thetaking off of or the' cutting I out of lines from theimultipleconduit line by theuse of speciallydesigned multiple conduit tiled sections which will permit the reaching of onlythe section of the multiple? line desired, either tota'keofi a line or to remove a line and restore the same to a con embodiment thereof'as illustrated in the accompanying drawings. In the drawings:

The horizontal pair ,of ducts 2 and 3 iSsepara'tedfrom the-horizontal pair of'ducts i and 5 by means'of small core-ways 10; The"- core-ways 10 and ducts 2, 3, 4 and 5 man formed at the same time by the use of a 'die through which the clay orlikematerial is forced. This manner of forming duct tile is well known in the art. The tile is cored;

, longitudinallyof its length during its formation to form a scoredli'ne8 along the tile,

In Figure 3 the same form of tile is illustratedwith the exception that the tile 1 illustratedin-Figure 2 is formed with 6 iIldB-j pendent ducts, 2 3 4 5?, l6 'and 17 The distributing'tile's 1 andl are of the same formation and this invention'is not limited to the formationofa tile including anynumber of (independent ducts, but any desired or. required number of ducts may be included in a single tileas is coinmon in the construction .of similar multiple conduit linesl; o. I The horizontal web 7* of the tile V1" is formed of greater thickness than the vertical i web 6? so as to permit a piano wire being run longitudinally of the tile 1 beforethe 'tile'is view of the distribuodied in this invention illus- I ,1 trating the same onareduced scale; i 7 multiple conduit lines it form of a conduit tile embodying this inven dried to form a slit 8 longitudinallyof the.

whole of the length of the tile extending longitudinally of the tile in the same manner as does the slit 8 in the case of the tile illustrated in Figure 2. This form of tile may be made up to include any desired number of ducts, depending upon the use of which such form oftile is desired to beput and the conditions of the particular conduit system.

Having fully described my invention, it is p to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims;

I claim: V a 1. A multiple duct conduit including exterior walls and a plurality of interior webs dividing said conduit into ducts, one ot-said webs being substantially twice the thickness of the exterior walls, said web "being coredto qfacilitate separation of the conduit through the-center of said web, the remaining-'webs being of a thickness not exceeding theithic-kness :ofthe exterior walls. a

2. A six -duct conduitincluding exterior wal'ls, a longitudinal web and two spaced;

transverse webs, one of said transverse webs beingsubstantially twice the thickness of the exterior wall, said web bein cored to facilitate separation of the con uit through the center of said .web, the remaining transverse Web and the longitudinal web being of less thickness than saidlexteriorwalls. During the formation-ofthe conduit tile 1,; insomecases it may be found desirable to score the tile at the endozf theslit 8, as *indi 3; A multiple duct conduit including ente- ,rior walls and interior webs in planes at wall, said web being scored to facilitate separation of the, conduit through the center of said web into two sections, the webs at right: anglesto such cored web' being ofiless thickness than said --exterior'walls. r
